Swimming, Lifting, running repeat....

Swimming, lifting, running, repeat...oh don't forget the 1hr core session either! As I continue to improve in these areas I seem to need more sleep as a result and over all I seem to have more muscle soreness! I thought that as you improved you were suppose to be less tired and sore, somehow my body missed this memo. I am going to attribute this all to the fact that I can push my self further as a result of my improvement.... I don't know how accurate this theory is but it doesn't matter I need something to explain it!
